I used EFB to make new update. I got my cpu key and everything from ftping. I then got nand from flash360. when I try to update it said something about not being "Zero-paired", I flashed anyway. now the console loads up to xbox logo, I can access screen with xbox botton, and scroll from settings to media, etc. If i try to go to games folder to boot xexmenu, or exit to dash it says if I exit current session I will lose unsaved progress. Then it just goes to black screen. Bad flash, I'm guessing. well I have access to xell reloaded. what do I do now?
